Hello,
I am trying to implement a python API in MATLAB to read position data from a motion capture system for feedback control. The python API works in terminal perfectly, but when I try to call it in MATLAB the position fails to update, which means to me there is something about how MATLAB calls python functions that is static (which is supported by the fact that when I update the python code, I need to restart MATLAB for the changes to take effect). Is there a workaround for this? Or some coder settings that I can tweak?
My code is supplied below:
The API call is simply
dataTest = py.mocapPosition.readSys;
And the python code is
import owlXYZ
import sys
SERVER = '192.168.1.230'
o = owlXYZ.Context()
# connect to server with timeout of 10000000 microseconds
o.open(SERVER, "timeout=100000")
# initialize session
o.initialize("streaming=1")
def readSys():
evt = o.nextEvent(100)
newlist = []
while evt.type_id != owlXYZ.Type.FRAME:
evt = o.nextEvent(100)
if "markers" in evt:
for m in evt.markers:
newlist.append(str(m))
print(m)
return newlist
elif evt.type_id == owlXYZ.Type.ERROR:
print(evt.name, evt.data)
elif evt.name == "done":
# done event is sent when master connection stops session
print("done")
# end main loop
def close():
# end session
o.done()
# close socket
o.close()
The header file owlXYZ supplies all the declarations necessary to import data from the server. All help is appreciated!
